Abstract:

In this paper, three different morphological Co3O4 electrodes for oxygen evolution reaction (OER) have been
synthesized. By comparing the three morphologies of Co3O4, the electrocatalytic properties show that the urchin-like
spheres of Co3O4 electrode has relative low overpotential and good electrocatalysis stability, indicating that the structure
of urchin-like Co3O4 spheres exhibit an easy OER for water splitting.
